Richard Biener <rguenth at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Target| |s390x Version|unknown |14.2.1 --- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> --- One common issue is that s390 ups the unrolling limit --params quite a bit, a "solution" is to add explicit --param max-completely-peel-times=16 (which is the default, but not for s390).
